1. A system for measuring bidirectional flow of fluid in a conduit comprising:

  • means incorporated in a conduit for creating a pressure differential in the fluid flowing in the conduit;

    a plurality of sensor means disposed partially within the conduit and positioned about the pressure differential creating means for measuring the pressure differential created by said pressure differential creating means and for producing signals indicative of the measurements, wherein at least one sensor means is disposed upstream of normal flow direction of the pressure differential creating means, at least one sensor means is disposed at the pressure differential creating means, and at least one sensor means is disposed downstream of the pressure differential creating means; and

    a control means for receiving signals from the sensor means and for computing flow direction and magnitude from the signals, including backflow magnitude from the pressure differential between the at least one sensor means disposed upstream and the at least one sensor means disposed at the pressure differential creating means, and the pressure differential between the at least one sensor disposed upstream and the at least one sensor means disposed downstream.
